產品結構
三筒式烘干機是通過對單筒烘干機的單筒體改為套疊在一起的三筒,以縮短烘干機體的外形尺寸。該機工作時,物料和熱氣流依次進入內至外筒體,在機體Z形往復折流后,充分利用熱能烘干物料后再卸出。
烘干機筒(tong)體(ti)部分由三個同(tong)軸水平(ping)放置的(de)(de)內、中、外筒(tong)套疊(die)組成,這就使筒(tong)體(ti)的(de)(de)截(jie)面(mian)得到充分的(de)(de)利用。其筒(tong)體(ti)外形總長度約為(wei)與(yu)之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大幅(fu)度地減少占(zhan)地面(mian)積和廠房建(jian)筑面(mian)積。
該機的支承(cheng)裝置,是在外筒(tong)上輪(lun)(lun)帶與托(tuo)輪(lun)(lun)支承(cheng),由電機直接帶動托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與輪(lun)(lun)帶摩擦,使筒(tong)體(ti)轉動。該機總體(ti)結構緊湊、合理(li)、簡單,為便于磨損件的檢修更換,在中間(jian)設計(ji)成軸向剖分式,用螺栓(shuan)固定連接。
工作(zuo)原理(li)
物料(liao)(liao)由(you)供(gong)料(liao)(liao)裝置進(jin)(jin)(jin)(jin)入(ru)回轉滾(gun)筒(tong)(tong)的(de)(de)內(nei)層(ceng)(ceng)(ceng),實(shi)(shi)現(xian)順流烘干(gan),物料(liao)(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)的(de)(de)抄(chao)板(ban)下(xia)(xia)不斷抄(chao)起、散落呈螺(luo)旋行(xing)進(jin)(jin)(jin)(jin)式(shi)實(shi)(shi)現(xian)熱交(jiao)換,物料(liao)(liao)移動至內(nei)層(ceng)(ceng)(ceng)的(de)(de)另一(yi)端(duan)進(jin)(jin)(jin)(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng),進(jin)(jin)(jin)(jin)行(xing)逆流烘干(gan),物料(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)不斷地被反復揚進(jin)(jin)(jin)(jin),呈進(jin)(jin)(jin)(jin)兩步退一(yi)步的(de)(de)行(xing)進(jin)(jin)(jin)(jin)方式(shi),物料(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)既充(chong)分(fen)吸(xi)收內(nei)層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)散發的(de)(de)熱量(liang),又(you)吸(xi)收中(zhong)層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)的(de)(de)熱量(liang),同時又(you)延(yan)長了干(gan)燥(zao)(zao)時間,物料(liao)(liao)在(zai)此(ci)達到(dao)(dao)干(gan)燥(zao)(zao)狀態。物料(liao)(liao)行(xing)至中(zhong)層(ceng)(ceng)(ceng)另一(yi)端(duan)而落入(ru)外(wai)層(ceng)(ceng)(ceng),物料(liao)(liao)在(zai)外(wai)層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)內(nei)呈矩形(xing)多回路方式(shi)行(xing)進(jin)(jin)(jin)(jin),達到(dao)(dao)干(gan)燥(zao)(zao)效果(guo)的(de)(de)物料(liao)(liao)在(zai)熱風作(zuo)用下(xia)(xia)快速(su)行(xing)進(jin)(jin)(jin)(jin)排出滾(gun)筒(tong)(tong),沒有(you)達到(dao)(dao)干(gan)燥(zao)(zao)效果(guo)的(de)(de)濕物料(liao)(liao)因自重而不能快速(su)行(xing)進(jin)(jin)(jin)(jin),物料(liao)(liao)在(zai)此(ci)矩形(xing)抄(chao)板(ban)內(nei)進(jin)(jin)(jin)(jin)行(xing)充(chong)分(fen)干(gan)燥(zao)(zao),由(you)此(ci)完成干(gan)燥(zao)(zao)目的(de)(de)。
